Apple has just sued Samsung for "copying" Apple's intellectual property in their devices. According to the WSJ, Apple named the Nexus S, Epic 4G, Galaxy S 4G and the Galaxy Tab tablet as evidence of Samsung stealing from Apple's iPhone and iPad. The lawsuit says:

"Rather than innovate and develop its own technology and a unique Samsung style for its smart phone products and computer tablets, Samsung chose to copy Apple's technology, user interface and innovative style in these infringing products."

Samsung joins HTC, Nokia and Motorola as companies that Apple has sued/is suing but the lawsuit with Samsung is particularly interesting because they have a business relationship: Apple uses Samsung manufactured parts in their devices! We'll have to wait and see how this lawsuit puts a strain on their relationship. [WSJ]
